Question

我正在尝试将此字符串拆分为数组，稍后将其转换为字典

let string = "test=1&name=Noodle&item=100"
let edit = string.components(separatedBy: "=")
// string.components(separatedBy: "=" && "&")???

但这只会将字符串用一个字符分开，即“ =“

我想要实现的是用两个字符“ =”和“＆”分隔字符串。我该如何实现？

Answer 1

您可以这样做：

func stringConvert(string: String) -> [String: Any] {

    let keysAndValues = string.components(separatedBy: "&")
    let arraysOfPairs = keysAndValues.map { $0.components(separatedBy: "=") }
    let tuples = arraysOfPairs.map { ($0[0], $0[1]) }
    let d = Dictionary(uniqueKeysWithValues: tuples)

    return d
}

let str = "test=1&name=Noodle&item=100"

let dict = stringConvert(string: str)
//["test": "1", "item": "100", "name": "Noodle"]

Answer 2

您所能做的就是替换字符串中出现的字符，然后将其分开

let string = "test=1&name=Noodle&item=100"

let edit = string.replacingOccurrences(of: "&", with: "=").components(separatedBy: "=")

快速通过2个不同字符动态分隔字符串
